CARBU'RETOR.

SPECIFICATION forming part of Letters Patent No. 359,585, dated March 15, 1887.

Application filed October 1, 1886. Serial No. 215,069. (No model.)

To all whom it may concern.-

Be it known that I, FERDINAND WEIL, of New York, in ,the county of New York and State of New York, have invented a new and useful Improvement in Carburetors, of which the following is a specification.

My invention relates to,carburetors for carbureting ordinary illuminating-gas by commingling with it the rich vapors of liquid by drocarbons for the purpose of increasing the illuminating power of such gas and effecting a saving in its use; and to this end it consists in the peculiar construction and arrangement of parts, which I will now proceed to describe with reference to the drawings, in which- Figure 1 is a central vertical section. Fig. 2 is a plan view in horizontal section through line as w,- and Fig. 3 is a detail showing a horizontal section of the reservoir-valve through line 3 y, Fig. 1.

A represents the outer, and A the inner, wall of an annular carburetingchamber.- The inner wall descends nearly to the bottom of the tank and is connected at the bottom to a central chamber, B, leaving, however, at the bottom an open space at a, which secures open communication between the annular carbureting-chamber. and the lower portion, A of the tank. The walls B of the central chamber rise to the level ofthe annular chamber and are covered over at the top, while a horizontal partition, G,separates the upper portion, B, of the central chamber from the lower portion, A

D is an equilibrium-pipe mounted upon the partition 0, and preserving always an open communication between the air-space in the top of tank A and the airspace in the top of 'reservoirchamber B. The lower chamber or tank, A", is filled with the liquid hydrocarbon, and as fast as it is absorbed by the gas in the annular chamber more of the liquid hydrocarbonfiis supplied from the chamber B, which acts as a reservoir-chamber. In this transfer it will be seen that the volume of liquid transferred from the higher to the lower chamber is compensated for by an automatic transfer of air from the lower tothe higher chamber. To permit the liquid contents of this reservoir to be transferred at will to the subj acent tank, a valve, E, whose stem rises to the top of the carburetor, is operated from the outside to allow the contents of the reservoir-chamber B to pass to the subjacent tank. The lower portion of this valve-stem is slotted or grooved longitudinally at g, and this portion rests in a seat, f, in the partition 0, which has an opening in its side communicating with the reservoir, so that whenthe stem E is turned to a position that brings its groove in registration with the slotin the side of the seat f the liquid hydrocarbon can pass through said registering-channelsfrom the reservoir above to the tank below, and when said stem is turned axially, so as to throw said channels out of registration, communication between the upper and lower chamber is closed.

To prevent the leakage of the hydrocarbon vapors at the joint which the valvestem E makes with the top of the reservoir, a disk or collar, 6, is formed on or attached to the stem, which fits closely down upon the top of the reservoir. A short vertical wall or flange, d, is also formed on the top of the carburetor around the dislg and a cap, d, is rigidly connected to the stem E, and is made to fit over and around the wall or flange d. The cup formed by this flange is then filled with some liquid which makes a perfectly tight joint.

In the walls of the reservoir B is a glass gage, L, and a similar gage, L, is arranged in the wall of the tank A in order that the level of the liquid may be observed.

At the top of the annular carburetingchamber is arranged a series of hooks, z,- or in the place of the same a ring or grating may be used, upon which-is suspended all around the annular chamber wicking F, which dips into the hydrocarbon below, and by taking up the same from capillary attraction gives a large superficial exposure for the absorption of the vapors by the gas.

From the top of the annular carburetingchamber there are two branch pipes, G G,

which rise from opposite sides of the chamber I and communicate with a case, H, in which there are two other branch pipes, II. Within the caseHis a plug-valve, J, having two channels, b and c, and a crank-handle, K, for turning it. I and I are the gas-pipes, of which I connects with the pipe at the meter and I with the distributing pipes of the house. 7

When the plug Jis turned, as shown, its channel-way b allows the gas to pass from pipe I to pipe 1 without going through the carburetor. When, however, said plug is turned to the position shown in dotted lines, channel-way b connects pipes I and G and channel-way c connects pipes I and G',and the gas entering at I passes down through the annular carbureting-chamber and over the candlewicking, and after absorbing a proportion of the vapors passes out at G and I,enriched as to its illuminating powers and increased in volume.

To fill the reservoir an inlet is provided in its top, which consists of an inner thimble and cap, N, and an outer and larger one, N, the space between which is filled with a liquid to make a sealed joint to prevent the escape of the hydrocarbon vapors.

After the carburetor has been in use for some time there will be a residuum of the heavier products, which are drawn off from time to time through a drain-cock, M, which, to prevent leakage, is covered by an inclosingcap containing a liquid seal.

The chief merit of my invention, as thus de scribed, is that the carbureting-chamber, by its special disposition, cannot be flooded by the accidental escape of oil from the reservoir, which carbureting-chamber, if flooded, would put out the lights of the building. This avoidance of flooding is effected in my invention by the relative altitudes and positions of the reservoir-chamber Band the annular wick-chamber, it beingimpossible for the contents of the reservoir B to rise to the top of the annular wick-chamber, and thus always insuring an open communication between the diametrieal pipes G G.

I do not claim, broadly, the four-way cock for passing the gas either through the carburetor or direct to the burners; but my special arrangement of the pipes in relation to the cock and the annular wick-chamber contributes to the advantages above referred to, and makes a compact and easily-constructed device.

Having thus described my invention, what I claim as new is- 1. A carburetor having a central reservoirchamber, an annular absorbent-chamber surrounding the reservoir and rising, substantially as described, to the highest level of the reservoir, an air pipe and valve for trans ferring from the reservoir to the absorbentchamber, and an inlet and outlet pipe for gas connecting with the absorbent-chamber above the level of the reservoir, substantially as shown and described.

2. In a carbureting apparatus, the combination of the vessel A, the walls A B, extending from the top nearly to the bottom and forming an annular outer chamber and an inner reservoir-chamber, communicating with each other at the bottom, the said inner chamber being provided with a horizontal partition, with valve and air-pipe for transferring the contents of the reservoir above to the space below, and the said annular chamber being provided with an absorbent, substantially as and for the purpose described.

3. In a earbureting apparatus, the combination of the vessel A, the walls AB, extending from the top nearly to the bottom and forming an annular outer chamber and an inner reservoir-chamber, communicating with each other at the bottom, the saidinner chamber being provided with a horizontal partition forming a reservoir above, with valve and airpipe for transferring the contents to the space below, the pipes G G, connecting diametrically with the opposite sides of the annular chamber, the casing H, with pipes I I, connecting with said pipes and located centrally above the carburetor, and the four-way cock J, substantially as shown and described.

The above specification of my invention signed by me in the presence of two subscribing witnesses.
